# vimd by Tuncay D.
# Select textfile in dmenu and open it in Vim.
#
# Usage:
#   vimd
# Or:
#   vimd DIRECTORY

# If TERMINAL is empty, then vim will be run directly.
# If TERMINAL is set to any value, it will use it as the terminal command to
# open a new window.
#
# Examples:
#   "alacritty -e", "xterm -e", "konsole -e", "gnome-terminal --",
#   "xfce4-terminal -e"
TERMINAL=
# TERMINAL="alacritty -e"

# Note: In case TERMINAL is not empty
# A few specific terminal require different quoting on execution.  So in
# case of such a terminal, edit the line at the end of the script from
#   $TERMINAL vim "$FILE"
# to
#   $TERMINAL "vim $FILE"
# The terminal "xfce-terminal" is known to require this.

# Default to current working directory, if no DIRECTORY was given.
if [ "$#" -eq "0" ]
then
    # Default folder to open in.
    DIRECTORY="."
else
    DIRECTORY="$1"
fi

# find: List all files from DIRECTORY, no folders.
# grep: Check if file is binary and get text files only.
# print: Print to stdout, so dmenu can catch the files.
# dmenu: Show a horizontal list of all found files.
